6 Claims.

mensions and conditions that are encountered in the trade and are very difiicult of adaptation to frames that are out of plumb or are not square, or where parts of the frame are of irregular shape or are excessively worn.

.An object of the present invention is to provide an insulating sash that is formed of parts that may be altered in dimensions and shape by the use of ordinary equipment at the site of the installation.

Another object is to provide a building insulating sash that is formed of parts that are largely produced by conventional equipment and that are easily shaped, worked and assembled with a minimum of labor and expense.

A further object is to provide a building insulating sash that has an outside weather surface that is resistant to the tendency of wind and water to be whipped thru apertures in the sash assembly during storm periods.

Another object is to provide an insulating sash that embodies suitable stress sustaining arrangements of parts that have proven eificient over long periods of use.

Another object is to provide an insulating sash that is admirably adapted for use in air conditioned buildings.

With the above and other objects in view, the present invention may be said to consist of constructions and arrangements of parts that will be understood by those skilled in the art to which the present invention pertains and. which is illustrated in the embodiment of the invention that is disclosed in the accompanying drawing, wherein:

Fig. 13 is a, broken away section of a modified form of sash bottom strip similar to that shown in Fig. 3.

In the accompanying drawing, the window casing or frame I and the window sill 2, that are positioned in the building wall 3, support the insulating sash that illustrates the subject matter of the present invention.

The sash frame portion of the insulating sash comprises the top strip 4, the pair of side strips 5, that are preferably continuous, and notched at the corners ina suitable manner for being bent, and the bottom strip 6 that is welded to the lower ends of the side strips 5.

The top strip 4 and each of the side strips 5, have an outwardly extending attaching portion 1, that may be cut away or altered in shape which a suitable outdoor sealing strip drawn tightly by the long wood screws l3 the sealing strip supporting leg, I 4.

i2 is about The L-shaped stop strip 15, that is secured to the top strip 4 by suitable means, such as by the metal joining screws I6, completes a groove that receives the upper edge of the upper glass panel ll. Similar L-shaped stop strips extend along each of the side strips 5, and are properly spaced from the T-portion ID of the side strips for the accommodation of two panels, as shown in Fig. 8.

The outdoor sealing strips l2, that extend along the top and two sides of 'the sash frame, join at the corners in any suitable manner, as by the simple overlap of ends shown in Fig. 4.

The sash frame bottom strip 6 is preferably of hollow sheet metal construction with an upwardly extending indoor fixed stop I! for the indoor engagement of the lower glass panel 18.

The adjustable sill sealing strip I9 is adjustably secured to the indoor side of the bottom strip 6 by suitable means, as by the screws [6, that are positioned in vertically extending slots lm in the sill sealing strip I9. The sill sealing strip l9 preferably has an indoor extending hand grip portion 20 along its upper edge and has a deformable window sill engaging and sealing portion, such as the outdoor extending window frame sill contacting portion 2|, along its lower edge that may be mechanically deformed on the job to cause it to conform to an irregular window sill, as where the window sill is higher at one end than it is at the other, is worn low at its midportion, or the like.

The frames of the upper glass panel H, the lower glass panel [8, and the screen panel 22, are preferably of solid extruded stock rigidly secured at the corners in any suitable manner, as by being welded together.

'The glass 23 in the glass panels II and I8, is preferably provided with permanent support on the indoor side to withstand wind pressures, in conformity with proper stress distribution and long established practice, and is secured in place on the outdoor side in any suitable manner that is adapted for the convenient replacement of the glass 23 on occasion, as by the use of glaziers points or wires, not shown, that extend into holes in the panel frame stock, and by the putty 24.

The upper glass panel II is preferably supported vertically by the screen panel 22, as shown in Fig. 11, and its lower frame carries suitable panel removing grip means, such as the screw driver tip receiving slot 25, that is accessible thru the tool admitting notch 26 in the upper frame stock of the screen panel 22. Where the presence of the screen panel 22 is not desired, other suitable upper glass panel supporting means may be provided, such as the supporting stop strips 21, that may be removably attached to the side strips 5 by the screws I6.

The lower glass panel l8 preferably has suitable hand gripping panel lifting means, such as the ring 28, that is carried 'by the overlapped strip 29, that is welded to the panel bottom frame stock. The lower glass panel l8 may be moved vertically to a desired position and secured at the desired elevation by operation of suitable means, such as the hand lever 30, that is rotatably secured to the side frame stock of the panel by the screw lid and that has the stop strip gripping inclined faced portion SI for gripping the stop strip I5 in increasing frictional compression.

In the screen panel 22,. the screen 32 is preferably secured to the screen panel frame in any suitable .manner, as by the tongued key strip 33 that draws the screen edge into the groove 34 in the screen panel frame on the tightening rotation of the screws IS.

A modified form of panel bottom strip 35 is shown in Fig. 13 of the drawing, that comprises two strips of stamped sheet metal with overlapping edges in place of the single strip of roll pressed sheet metal that is shown in Fig. 3.

It is to be understood that the particular constructions of parts that are shown and described herein are presented for purposes of illustration and explanation and that various modifications in the means for accomplishing a. given function may be made without departing from the invention as defined in the appended claims.
